I'm a noob riding a hardtail, rigid fork cro-mo Gary Fisher on some highly technical trails with serious rocks and roots. I've ridden with a suspension fork, but never got comfortable with the feeling of instability when braking. Never tried a rear suspension bike at all. Is it a metter of comfort or control? I don't mind hitting the ground hard and I'm running 2.5" tires, but I was thinking suspension must help keep you from bouncing off the ground.
